What Qualifies as More Sustainable Work Clothing?
As with all things sustainable fashion, there are a lot of layers to it!
Secondhand Workwear
First off, repurposing what you have and shopping secondhand is always a good idea. It’s also often more affordable.
But it tends to be quite tough to find something like quality well-fitting workwear from a thrift shop. So you might want to try a searchable marketplace, such as:
- The RealReal (more premium brands and prices)
- thredUP (sells all types of brands). This online consignment store even has a workwear thrift shop collection, making it easier to find items like secondhand trousers, sheath dresses, blouses, and loafers.
Responsible Materials and Production
When shopping for new more sustainable workwear, here’s the criteria I’m looking for:
- Certified — or otherwise guaranteed — organic natural fibers (if using synthetics, then they should be recycled, but I do tend towards natural fibers over even recycled synthetics due to concerns about microplastics and my own skin health)
- Traceability throughout the brand’s supply chain,
- Transparency around their environmental impact with clear goals and progress towards reducing that impact
- A commitment to genuine partnerships with supplier factories and farms, and assurance of fair worker wages
- Prioritization of quality over quantity
- Circularity efforts such as repair programs and resale options
Where to Find More Sustainable Workwear
These slow fashion brands have button-ups and blazers, well-fitted trousers, silky blouses, and sheath dresses suitable for a formal dress code and some sustainable workwear-inspired options for a business casual dress code.

We love a brand that has sustainability commitments as bold as its’ marketing. As the Swedish brand writes: “the world doesn’t need another fashion brand.” That’s why ASKET is committed to doing less, better. Instead of churning out new styles every season, the brand has a permanent collection so they can obsess over creating the best fit and using the best fibers for those pieces. Now that’s slow fashion. The brand
6. Encircled
